5/3-way air operated valve, closed centre, G 1/4, pilot ports 2x G 1/8, 590 l/min - YPC SFP4303

The YPC SFP4303 is an air operated 5/3-way valve with closed centre. When pilot pressure at both G 1/8 ports is gone, the springs centre the spool and the actuator holds its position. Flow through G 1/4 is 590 l/min.

Advantages

• Spring-centred position with all ports blocked, operating pressure 2 to 10 bar.
• Effective area 19.0 mm² according to YPC, same body style as the SF series solenoid valves.
• Purely pneumatic actuation with 2 to 8 bar pilot pressure, no electrical energy is needed at the valve.
• Oil-free operation: no lubrication required, if lubricated use ISO VG32 oil.
• Body and spool in aluminium, NBR seals, pilot section in glass fibre reinforced polyamide.

Applications

• Medium bore cylinders in fixtures and feeders with G 1/4 lines.
• Holding loads once both pilot signals have dropped.
• Stopping a cylinder in an intermediate position in a purely pneumatic control.
